The values of k and m for which the given system has infinitely many solutions are k = 6 and m = -7

To find the values of k and m for which the given system has infinitely many solutions, we can analyze the coefficients of the variables and the constant terms.

Given system:

\(\[\begin{align*}\\3a + 2b &= 2, \\6a + 2b &= k - 3a - mb.\end{align*}\]\)

To determine when this occurs, we can compare the constant terms. The constant term on the right side of the second equation is k, while the constant term on the left side is\(\(-3a - mb\)\). For the lines to coincide, the constant terms should be equal.

So, we have\(\(k = -3a - mb\).\)

Now, we can substitute the values of \(\(a\)\) and \(\(b\)\) from the first equation into this equation to eliminate \(\(a\)\) and \(\(b\)\)

\(\[-3a - mb = -3(2b - 2) - mb = -6b + 6 - mb = -6b - mb + 6.\]\)

Comparing this expression with k, we get -6b - mb + 6 = k

Simplifying further, we have -7b - mb = k - 6

Now, we can equate the coefficients of b on both sides:

-7 - m = 0

This gives us m = -7

Substituting this value of m back into the equation -7b - mb = k - 6, we get -7b + 7b = k - 6, which simplifies to 0 = k - 6

Thus, k = 6

Therefore, the values of k and m for which the given system has infinitely many solutions are k = 6 and m = -7

Answer:

\( \frac{11}{12} > \frac{11}{13} \)

Step-by-step explanation:

Here , the fraction has same numerators but the denominators are different. Whenever any 2 fractions have same numerator but diffeent denominators , the fraction whose denominator is less is greater than the fraction whose denominator is more.

Here 11 is common in both the numerators but when we talk about denominators , 12 < 13 . So,

\( \frac{11}{12} > \frac{11}{13} \)

Verification :-

\( \frac{11}{12} = 0.9166666667 = 0.91(appx)\)

\( \frac{11}{13} = 0.8461538462 = 0.84(appx)\)

Answer: $227,226.51

Step-by-step explanation:

First, we need to convert the period to weeks.

9 1/2 years = 9.5 years

1 year = 52 weeks

9.5 years = 494 weeks

Next, we can use the formula for the future value of an annuity:

FV = (PMT x (((1 + r/n)^(n*t)) - 1)) / (r/n)

where:

PMT = payment amount per period

r = annual interest rate

n = number of compounding periods per year

t = number of years

Plugging in the given values:

PMT = $300

r = 0.055 (5.5% expressed as a decimal)

n = 52 (compounded weekly)

t = 9.5 years = 494 weeks

FV = ($300 x (((1 + 0.055/52)^(52*494)) - 1)) / (0.055/52)

FV = $227,226.51

Therefore, the future value of the annuity is approximately $227,226.51.

I would think about it as adding 15 and 9, but just make the answer negative.

The transformation of the function is illustrated below

Parent function is: f(x) = 2x - 6

Transformations are:

shifts f(x) 4 units down

f(x) → f(x) - 4 ⇒ g(x)= 2x - 6 - 4 = 2x - 10

stretches f(x) by a factor of 4 away from the x-axis

f(x) → 4*f(x) ⇒ g(x) = 4(2x - 6) = 8x - 24

shifts f(x) 4 units right

f(x) → f(x - 4) ⇒ g(x) = 2(x - 4) - 6 = 2x - 14

compresses f(x) by a factor of toward the y-axis (must be 4)

Interest equals 10,000 times 5% times 5 years

$2500  is the total interest.

The total loan to be paid after the tenure of 5 yrs will be $12500 and the interest incurred is $2500.

Simple interest is the cost of borrowing money without accounting for the effects of compounding.

Given is a loan at a principal amount of $10,000 at a rate of 5% for 5 years.

The total amount [A] to be paid after the tenure of 5 yrs will be -

A = P(1 + rt)

A = 10000(1 + 0.05 x 5)

A = 12500

The amount of interest incurred = A - P = 12500 - 10000 = 2500

Therefore, the total loan to be paid after the tenure of 5 yrs will be $12500 and the interest incurred is $2500.

Answer:

C. a quadratic function with a negative value of a

Step-by-step explanation:

It is likely that a quadratic function with a negative value of a would be the best model for this data, as it would represent a parabolic shape that can accommodate a downward trend, followed by an upward trend, in the stock price. The value of "a" determines the direction of the parabola, with a negative value resulting in a downward-facing parabola, which is appropriate for a stock price that starts low and increases over time. This type of function would provide a good fit for the data, especially if there are fluctuations or ups and downs in the stock price over time.

The loss percentage is 91%.Given that Venessa bought 80 apples for 4$, out of these apples, 25% were rotten and had to be thrown away. Venessa sold the remaining apples at 6 cents per apple.To calculate the profit or loss percentage, we need to determine the cost price, selling price, and the number of apples sold.

Cost price (CP) = 4 $.Selling price (SP) = 80 × 0.75 × 6 cents= 36 cents = 0.36 $.Now, let's calculate the profit.Profit = SP – CP= 0.36 $ – 4 $= – 3.64 $Loss = CP – SP= 4 $ – 0.36 $= 3.64 $.

Therefore, Venessa incurred a loss of $3.64 when she sold 80 apples at 6 cents per apple.Now let's calculate the loss percentage Loss Percentage = (Loss / CP) × 100= (3.64 / 4) × 100= 91%.

Therefore, the loss percentage is 91%.Note: If the result obtained after the subtraction of SP from CP is negative, it means there is a loss, and the percentage of loss can be calculated by (loss/CP) × 100.

Answer:

One piece of pizza = $2.5

One candy bar = $1

Step-by-step explanation:

Call 1 pizza a, 1 candy bar b. We have:

2a + 3b = $8

=> 3(2a+3b) = 3. $8

= 6a + 9b = $24

and

6a + 5b = $20

=> (6a + 9b) - (6a + 5b) = 9b - 5b = 4b = $24 - $20 = $4

=> b = $1

=> 2a + $3 = $8

=> 2a = $5

=> a = $2.5

So one piece of pizza = $2.5, one candy bar = $1

Daniela's graph of the function describing Monday's storm depicted the storm's temporal evolution, showcasing the changing intensity of rainfall, intermittent spikes, shifting wind direction, and overall duration. Analyzing the graph allowed Daniela to gain insights into the storm's behavior and better understand its impact on the area.

Daniela graphed the function describing Monday's storm and observed several key features. The graph displayed a rapid increase in precipitation during the early morning hours, with rain intensifying steadily until reaching its peak around midday. Afterward, the precipitation gradually subsided, leading to a decline in rainfall amounts throughout the afternoon and evening.

The graph exhibited a distinct pattern of fluctuation, reflecting the storm's dynamic nature. Intermittent spikes in rainfall were visible, indicating periodic bursts of heavy precipitation throughout the day. These spikes were followed by brief periods of relative calm, during which the rainfall decreased temporarily before resuming its intensity.

Furthermore, Daniela noticed a gradual shift in wind direction as the storm progressed. Initially, the wind blew from the east, but it gradually veered towards the south as the storm system moved across the region. The change in wind direction was evident on the graph, showing a gradual rotation of the wind vector over time.

The graph also revealed the storm's duration, spanning from the early morning hours until late evening. The rainfall accumulation steadily increased during the storm's initial phase and reached a maximum before gradually tapering off towards the end of the day.

Answer:

Step-by-step explanation:

(a) To find the N-intercept, we set t to 0 in the equation N = -0.3t + 250:

N = -0.3(0) + 250

N = 250

Therefore, the N-intercept is (0, 250).

(b) The N-intercept is the point on the graph where the tuition is $0 and represents the number of students who would enroll in the basketball camp if it were free. In this case, if the tuition was $0, 250 students would enroll in the basketball camp.

(c) To find the t-intercept, we set N to 0 in the equation N = -0.3t + 250 and solve for t:

0 = -0.3t + 250

0.3t = 250

t = 250/0.3

t ≈ 833.33

Therefore, the t-intercept is approximately (833.33, 0).

(d) The t-intercept is the point on the graph where the number of students who enroll in the basketball camp is zero and represents the tuition that would need to be charged for no students to enroll. In this case, if the tuition was approximately $833.33, no students would enroll in the basketball camp.

Required

Determine the inverse

\(g(n) = -3n - 1\)

Replace g(n) with y

\(y = -3n - 1\)

Swap positions of x and y

\(n = -3y - 1\)

Make y the subject

\(3y = -n - 1\)

\(3y = -(n + 1)\)

\(y = -\frac{n+1}{3}\)

Replace y with g'(n)

\(g'(n) = -\frac{n+1}{3}\)
